cervantes, you are The Man. I've been searching for a succinct explanation of the 5D3's celebrated AF system with regards to BIF ever since I purchased the body a little over a year ago. Even the Canon tutorials on youtube are far less valuable than your advice. Thank you very, very much. I'm sure this took a fair amount of your time and those of us here on the forum appreciate it.
Your specific advice for AF settings was excellent, but I'd also like to hear your take on some other settings. As I work my way into shooting BIF, alone and without benefit of workshops or books, I've concluded that keeping the shutter speed high enough and aperture wide enough can only be accomplished in Manual mode. Av invariably gives me an unacceptably slow shutter speed (motion blur) while Tv often fails to select an appropriate aperture. That means Auto ISO must jump in there to make sure my defined shutter speed and desired aperture results in a proper exposure.
As previously mentioned by yourself and others, we need Canon to give us a firmware update that allows Exposure Compensation when shooting in M mode and Auto ISO, especially with birds due to the overwhelming brightness of the sky. But given this handicap, would you still advise shooting M and using Auto ISO? And if so, what ISO limits do you like? If not, how else do you approach the speed/aperture/exposure/noise conundrum when it comes to shooting feathered rockets?
ONE MORE QUESTION
I have my C3 parked with the following settings for BIF (in addition to making changes to my AF and AF-ON per your excellent instructions), please review and offer suggestions as this is the fast-dial place from which I start: Manual mode, 1/1000, f/5.6, Auto ISO, AWB, AI Servo, Evaluative metering, High-Speed shutter, 1000X 32GB CF only (SD card removed to improve buffer dump), RAW
Note that I'm typically outfitted with a 5D3 body and a 400 f/5.6 L prime lens or sometimes my 70-300 L zoom, with or without a Kenko 1.4X teleconverter, on and off tripod. I'm saving for a 600mm, but alas, that may be a long wait...
Thanks again for offering your advice and for the helpful members who've chimed in with their 2 cents.
